Description

Technical Field

[0001] The utility model belongs to the technical field of PCB boards, and particularly relates to a PCB board continuous detection device. Background Art

[0002] PCB is called printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board. Its main function is to connect various electronic components through circuits, play a role in conduction and transmission, and is a key electronic interconnection part of electronic products. Almost every electronic device cannot do without a printed circuit board, because it provides mechanical support for the fixed assembly of various electronic components, realizes the wiring and electrical connection or electrical insulation between them, and provides the required electrical characteristics. Its manufacturing quality directly affects the stability and service life of electronic products, and affects the overall competitiveness of system products.

[0003] Currently, PCB boards need to be inspected as a whole after production is completed. The inspection includes inspection of each position of the board surface and power-on inspection. However, for large-area PCB boards, flipping them back and forth for inspection can easily damage the board surface and cause it to be scrapped. At the same time, manual inspection is a waste of labor costs. Summary of the invention

[0007] The conveying assembly includes a first driving element and a belt transmission structure connected to the first driving element, and the belt transmission structure drives the PCB to move along the X-axis;

[0008] The first clamping assembly includes a first clamping member and a slider, and the first clamping member is slidably connected to the frame body along the Y axis through the slider;

[0009] The second clamping assembly includes a second clamping seat plate sliding along the Y-axis on the frame body and a second clamping member mounted on the second clamping seat plate;

[0010] The third clamping assembly includes a third clamping seat plate that slides along the Y-axis on the main body of the frame and a third clamping member mounted on the third clamping seat plate.

[0011] Further, the conveying assembly further includes a guiding structure for guiding the PCB board;

[0012] The guiding structure is a clamping plate provided with a groove for accommodating the PCB board, and the guiding structure is fixed to the first clamping assembly.

[0013] Further, the first clamping member includes a first clamping plate and a second clamping plate, and further includes a first driving plate for driving the second clamping plate and the first clamping plate to clamp. The driving plate is fixedly connected to the second driving element. When the second driving element drives the first driving plate to move along the X-axis, the second clamping plate and the first clamping plate can be driven to clamp / loosen.

[0014] Further, the second clamping member includes a third clamping plate and a fourth clamping plate that slide on the second clamping seat plate, and further includes a second driving plate for driving the fourth clamping plate. The second driving plate is connected to the third driving element. The third clamping plate is provided with a plurality of guiding columns. When the third driving element drives the second driving plate, the third clamping plate and the fourth clamping plate can be driven to clamp / loosen.
